JOHN F. LAUTH, OF READING, PENNSYLVZANIAr IMPROVEMENT IN MACHINERY FORROLLING IRON.

Specification forming part of Letters Patent No. 53,012, dated March 6,1866.

To all whom it may concern:

Be it known that I, JOHN F. LAUTH, of Reading, in the county of Berksand State of Pennsylvania, have invented a new and useful Improvement inMachinery for Bolling Iron; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable thoseskilled in the art to make and use the same, reference being had to theaccompanying drawings, forming part of this specification, in which-Figure 1, Sheet No. l, is a front elevation of my invention; Fig. 2,Sheet No. 2, an end view of the same; Fig. 3, a transverse verticalsection of the same, taken in the line x Fig. 1;.Fig. 4f, an end view ofthe same, the end opposite to that shown in Fig. 2.

Similar letters of reference indicate corresponding parts.

This invention relates to a new and useful improvement in machinery forrolling iron; and it consists in the application of side rollers to theordinary rollingmachines, whereby the edges of the metal, both previousto its passage between the rollers and after leaving the same, aresubjected to pressure, causing the metal to be rolled of a uniform widththroughout and with smooth edges.

The invention also consists in a novel means employed for operating andadjusting the side rollers, as hereinafter fully shown and described,whereby said rollers may be placed at av greater orless distance apartto suit the width of the metal being rolled, and the rollers at thedischarge side of the pressure-rollers made to rotate with a greaterspeed than those at the feed side.

A represents a framing, which may be const-ructed in any proper mannerto support the working parts 5 and B B are two horizontalpressure-rollers placed in said framing, one over the other in the sameaxial plane.

The pressure of these rollers upon the iron passing between them may beregulated as desired by means of screws C C, which pass or work throughnuts a in the framing, and have motion communicated to them through themedium of gears D from a shaft, E, as shown clearly in Fig. l.

F F F F represent side rollers, which are placed on vertical shafts G inthe framing A. The bearings b of these shafts G are fitted betweenguides c c in the framing A, as shown clearly in Fig. 3, and the upperends of the shafts G have bevelwheels H upon them which gear intocorresponding wheels I on horizontal shafts J on the upper part of theframing A.

The wheels I are allowed to slide freely on the shafts J, and saidwheels have grooves d made ciroumferentiallyin their hubs to receive theupper ends of the shafts G.

By this arrangement it will be seen that the side rollers, F F F F', maybe adjusted nearer together or farther apart without at all interferin gwith their driving mechanism as the wheels I are carried along on theirshafts J, in consequence of the upper ends of the rollershafts G fittingin the grooves d of the wheels I, said wheels being fitted on the shaftsJ by -means of a feather and groove to admit ofthe former sliding on thelatter and still be turned by them.

v The rollers F F F F are placed one pair, F F, at the feed side of therollers B B, and the other pair at the discharge side thereof, and theyare adjusted by means of screws K, which pass horizontally through theframing A into the bearings b, said screws having their outer bearingsin plates L at the sides of the framing and connected, by gears e, withshafts M. By this means the lateral adjustment ofthe side rollers, F F FF, may be readily effected to suit the width of the iron being rolled.

The rollers F F at the feed side of the press ure-rollers B B are nearertogether than those F at the discharge side, and the latter rollers havea quicker motion than the former ones. This is necessary, as the iron asit is rolled and reduced in thickness has a quicker motion at thedischarge side. This difference in the motion ofthe two pairs of siderollers, F F F' F', is effected through the medium of the gears N,(shown clearly in Fig. 2,) the difference in the size of these gearscausing the shaft J which rotates the rollers F, working faster than theother shaft J, whichrotates the rollers F.

The whole arrangement is extremely simple and efficient, and is a greatacquisition to the ordinary pressure-roller devices for rolling iron.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of the mainvrolls B B and twopairs of side rollers, F F F F', constrneted and arranged substantiallyas and motion `them the rollers F at the feed side of for the purposesset forth. the same, substantially as and for the purpose 2.
